Will Pope Francis bless with the Sign of the Cross?

An occasion described as absolutely unique, at 6 pm Rome time on March 27 - alone - Pope Francis will preside over a moment of prayer concluded with his imparting the “Urbi et Orbi” blessing that is typically reserved for the elected Successor of Peter, at Christmas, and at Easter.

"We want to respond to the pandemic of the virus with the universality of prayer, of compassion, of tenderness, Let us remain united. Let us make our closeness felt toward those persons who are the most lonely and tried," Pope Francis said.

Will Pope Francis impart his blessing with the Sign of the Cross? If so, why? If he does not, will anyone notice or care?
